To all whom it may concern.-

Be it known that I, GRIFFITH HUNTER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Apparatus for Hoisting and Laying Stone, of which the following is a specification.

The object of the present invention isto provide an apparatus for facilitating the operation of hoisting, moving into place, and laying heavy stones; andto this end my invention consists in a Windlass for raising the stone, mounted on a movable frame, which is provided at one end with two pairs of truckwheels, the inner higher pair of which having a swiveling axle, so that the device may be readily guided when supported on the swiveling truck-wheels, and the outer pair of wheels being adapted to support the frame upon suitable tracks astride the wall wherein the stones are to be laid, the windlassframe proper being itself adjustable transversely on the truckframe on which it is supported. The truckframe is also provided with suitable platforms for the men operating the machine. The rear end of the truck-frameis provided with a swing ing derrick, by means of which stones or. col- 11 111118 may be laid in the foundations of bridges, or places where it is impracticable to support the truck astride the wall.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts through out the several figures, Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a front end elevation of the same. Fig. 3 is aside elevation, and Fig. 4is a plan View. In Figs. 1 and 2 the swinging derrick is removed.

In said drawings, A represents the truckframe, consisting essentially of a pair of Iongitudinal beams, a a, on each side, between which the outside wheels, B, are hung in suitable bearin s crossieces a )osts a braces a brace-rods a, and upper rectangular frame, a The front end of the truck A is supported upon a pair of truck-wheels, O 0, whose axle O is' journaled in a swiveling frame or fifthwheel, 0, which is provided with a tongue, 0 for guiding the truck. The Windlass-frame D ,astride the wall,'the apparatus may be easily rests upon this rectangular frame 0?, and it is provided with small rollers 67, so that the frame may be easily moved transversely on the rectangular frame. The transverse pieces of the rectangular frame are provided with racks E E, and the Windlass-frame is provided with a shaft, 6, a crank, e, for turning the same, and spur-wheels or pinions e", which engage with the racks, wherebythe Windlass maybe moved or adjusted transversely in laying the stones.

F represents the Windlass, which may be driven by power or by hand through the spurwheelsff and crank f.

G represents the block and tackle, which is provided with suitable grappling devices.

The racks E E are secured to the inside of the frame and project slightly above its surface, so that theyserve as a guide to the windlass-frame in its transverse motion.

H is a swinging or gallows derrick, having a hinge or loose hearing, it, for the foot of the derrick at the rear end of the truck-frame.

K K are the guy-ropes,- which are secured at one end to the top of thederrick, and at the other to the front end of the truck-frame.

The Windlass-frame, when the derrick is being used, is turned around on the truck-frame in the position shown in Figs. 3 and 4, and secured in place thereon by clamps or stirrups 7t it, which bind the Windlass-frame to the truckframe.

By reason of the inner higher pair of swiveling truck-wheels, which support the front end of the apparatus, except when it is run guided or moved to any place desired. If the stones to be laid happen to be at some distance from the wall, a team of horses may be employed to move the apparatus to and from the approach to the wall. In operation a platform or track for the outside truck-wheels is erected on each side of the wall to support the apparatus. When the apparatus is moved over or astride the wall the inner or swiveling truck-Wheels are simply suspended vfrom the 5 apparatus above the wall. In setting the stones the stone is brought into the desired position longitndinallyon the vwall by moving the truck forward or back on the track, and into position transversely by moving the Windlass-frame I00 transversely on the truck-frame by means of the rack and pinion and crank for operating the same.

L and L are platforms on each side of the Windlass-frame for the men to stand upon in operating the Windlass. The platform L is hinged to the truck-frame, so as to not interi'ere with elevating the derrick.
